Glioblastoma stem cells (GSCs) are thought to contribute to the diffuse invasiveness of malignant gliomas. Emerging evidence supports a role for a disintegrin and metalloproteinase 17 (ADAM17) in proteolytic ectodomain shedding of several EGFR-binding ligands, which subsequently activate PI3K/AKT and MEK/ERK pathways through EGFR phosphorylation thus(More)
Dendritic cells (DCs) are potent antigen-presenting cells (APCs) that are characterized by the ability to take up and process antigens and prime T cell responses. Mesenchymal stem cells (MSCs) are multipotent cells that have been shown to have immunomodulatory abilities, including inhibition of DC maturation and function in vivo and in vitro; however, the(More)
Dendritic cells (DCs) are potent antigen-presenting cells that play a critical role in priming tumor immune responses. We investigated the mechanisms of antitumor efficacy of DCs pulsed with argon-helium-cryotreated glioma cells. There was significant upregulation of maturation markers (CD80, CD86, MHC-I, and MHC-II) in argon-helium freeze-thawed(More)
Based on percolation mechanism of fractured reservoirs and simulation technique, the numerical simulation software of fractured reservoirs has been developed on PC-Linux environment, which is on the basis of DQHY simulator of three dimensions and three phases. It can treat dual-porosity/singlepermeability and dual-porosity/dual-permeability model. The(More)
Going through the development more than forty years, the overall water-cut to Daqing Oilfield has almost reached 90%. But there is still considerable residual oil in the place. Reservoir engineers want to know the residual oil spatial distribution and how to dig it. This requires large-scale reservoir simulation within limited time. Enlarged scale and(More)
Immune responsive gene 1 (IRG1) is highly expressed in mammalian macrophages during inflammation. However, the role of IRG1 in tumorigenesis remains unclear. In the present study, we aimed to clarify the epigenetic regulation and biological functions of IRG1 in glioma. We found that the expression level of IRG1 influenced the WHO stage in 140 glioma(More)
Dendritic cells (DCs) are highly specialized antigen-presenting cells that play a key role in the activation of naive T cells. With an aim to explore whether in-situ administration of DCs following argon-helium cryosurgery could enhance specific antiglioma immunity in mice, we evaluated the validity of this approach in a murine subcutaneous GL261 glioma(More)
OBJECTIVE This study is to investigate the in vivo apoptotic processes in glioma tissues following cryoablation and the effects of glioma tissue extracts on GL261 glioma cells in vitro. METHODS TUNEL and flow cytometry analysis were performed to detect the apoptotic processes in the glioma tissues following cryoablation and in the GL261 cells treated with(More)
Glioma is the most common malignant primary brain tumor, and it has a poor prognosis. Studies have shown that cryoablation can activate antitumor immunoeffects by promoting the augmentation of dendritic cells (DCs). Granulocyte macrophage colony-stimulating factor (GM-CSF) has been shown to be useful for immunotherapy against glioma because it can stimulate(More)
